给定一个 string，将其偶数索引和奇数索引字符作为空格分隔的字符串打印在一行上

Question

Given a string, print its even-indexed and odd-indexed characters as space-separated strings on a single line.

Example:

s = adbecf => Print abc def

My approach:

 t = input() p = len(t) for i in range(p): s = t[i] n = len(s) even = [] odd = [] for j in range(n): if j % 2 == 0: even.append(s[j]) for j in range(n): if j % 2:= 0. odd.append(s[j]) first_join=''.join(even) second_join = ''.join(odd) print("{} {}",format(first_join second_join)

Answer 1

No need to use complex ways. here is a easy way to do it.

 t = input() p = len(t) ans = "" # create empty string for i in range(0,p,2): ans += t[i] # Add even characters ans += " " # Add space. for j in range(1,p,2): ans += t[j] # Add odd characters print(ans)

Input: adbecf

Output: abc def
